Isaac newton laws of motion3/11/2023 ![]() Tweetie is (marginally) lighter after his laps, so he will be (marginally) less inclined to resist change. We now know something heavier resists change more strongly. The question asks about Tweetie’s inclination to resist change. Is he now less inclined or more inclined to resist change in motion? Let’s pay attention to the wording here. Tweetie ends up losing 0.1 g of fat while flying his square loop so many times. ![]() Except that it’s also true for couch potatoes moving at constant velocity, this analogy is great. If we’re vegetating on a couch, perhaps eating potato chips, we won’t be inclined to move at all. We could also think of the First Law as the Couch Potato Law. That’s the whole philosophy behind what charging linebackers do. The more mass something has, the harder it is to get it moving or stop it once it’s whizzing through the universe. In literature, previous science classes, or by personal experience. We may or may not have run into this idea in our other lives. Inertial mass is the measure of an object’s resistance to acceleration, the resistance to a change in motion. This law is frequently referred to as the law of inertia, where inertia is a property of mass, which in turn is a property of how much of a substance there is. Without outside influences (forces) the motion doesn’t change by its very nature. ![]() We caught a glimpse of this in the horizontal movement of a projectile. And by “motion,” we mean constant motion: an unchanging velocity. Newton’s First Law of Motion says that an object at rest tends to stay at rest, while an object in motion tends to stay in motion. We thank him less for developing calculus along the way, too. In reviewing the work of Copernicus, Galileo, and Kepler, Isaac Newton connected their dots and came up with three laws of motion, first published in 1687, for which we are forever in his debt.
